Think its pretty cool, but as long as the coin is not on the exchange, I'm not sure what return to expect.
You can see how the system works, basically jsecoin just like any other project, jsecoin has a form value paltform in the form of a token.
I think it looks like doing mining by buying some hashrates on the system, basically it can be said as a mining with cloud system, I am very worried about the system because most of them often have big risks.
If you say about referrals that can make you earn more money then it is the hallmark of the system I mentioned, it is profitable but you have to try hard to attract users and then the results you get do not have any certainty, once again please read first so that what you do is not in vain.
note: I have such an opinion because I've experienced a bad thing with some almost similar schemes, everyone has experienced different things and everyone is entitled to give his opinion.
